When I first got an ereader I read a police type book it could have been a series I can't remember and I seem to remember I enjoyed it but can't remember much about it.
It started off with a woman who had a problem and had to call the police, she owned a Beauty Salon or a Gym, it was set in the US but not sure where and she ended up in a relationship with the detective guy, I think someone may have tried to kill her...
Reading that back there's not much to go on but it's been driving me crazy
